Thank you @merej99, not only for the encouraging comment and upvote, but also for the great perspective added on. :c)

I too find Abraham Maslow's Hierarchy of Needs to be a useful point of reference at times. I sincerely believe that species# behaviors shift on the basis of fulfillment of each level - with some species being more susceptible - and evolved (or evolved in a society-compattible manner), than others.

A dog that is not hungry is less likely to act in aggression. Similar also for cats, but a viper may still lash out at the hand that feeds it if given a chance. And even well-fed kitties might hunt birds for sport.

Of course there does exist a flipside of having a need met for as longas one can remember. Taking it for granted is one possibility.

Your verbalized dwelling upon the subject matter reveals to me that you are well ahead of the curve. Good on you. :c) And thanks again for the comment! ^_^
